CHARLES E. DAILEY, $3., OF PITTSBURGH, PENNSYLVANIA.-

LAMP-TURNING MECHANISM.

Application filed December 30, 1918.

To all whom it may concern:

Be it known that 1, CHARLES E. DAILEY, Sn, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Lamp- Turning Mechanism, of which the following is a specification.

This invention relates to mechanism for turning lamps, and more particularly automobile lamps, and has for its primary object to provide mechanism whereby the lamps will automatically follow the contour of a road and are capable of being swung vertically for varying the travel of the rays of light.

in object of the invention is to provide two sets of mechanism acting independently of each other one manually operated and the other automatically operated for swinging the head lamps in two directions.

Besides the above my invention is distinguished in the novel manner of tilting the lamps so that the rays of light thereof will not effect the driver of an approaching car.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:

Figure 1 is a side elevation of the device shown somewhat enlarged for the purpose of illustration.

Fig. 2 is an enlarged view of a portion of the mechanism.

Fig. 3 is a detailed sectional view through a portion of the operating link.

Fig. 4 is a top plan view of the mechanism with one of the lamps removed.

Fig. 5 is a detailed sectional view through a portion of the lamp showing its pivotal connection.

Fig. 6 is a detailed perspective view of a portion of the operating mechanism.

Again referring to the drawings which illustrate my invention in one of its forms the numeral 1 designates the lamps of a pair of head lamps each having an inclined lens for restricting the direction of the travel of the light rays. As clearly shown in Fig. 5 the lamp 1 has riveted thereto ears 2, each having a pivotal connection with a bracket 3. This bracket 3 is rigidly connected to a shaft 4 mounted for rotation in a frame 5 secured in any suitable manner to the frame of an automobile. I'he frame 5 is provided Specification of Letters Patent.

with a projection 6 forming a bearing for centric with shaft 4 and is rigidly secured to cars 2 with a result that whenmovement 1s given to the link 10 the lamp 1 will be tilted or rocked vertically owing to its pivotal connection with the bracket 3.

As far as I have proceeded it will be seen that the lamp 1 may have its light rays thrown directly in front of the front wheels of the'machine or elevated above the machine, as desired. For giving movement to the gear 7 I have shown one form of mechanism that has proved practical and which is manually operated. This mechanism consists of a segmental gear 13 meshing with the gear 7. The shaft 14 of the gear 13 is keyed to a slotted lever 15, the slot 16 of which engages .a pin 17 on an arm 18. The arm 18 associated with each lamp, is rigidly connected to a horizontally disposed rotatably mounted shaft 19 passing trans versely across the frame of the automobile. This shaft has projecting therefrom an arm 20 having a pivotal connection with any suitable form of link mechanism 21 that may be manually operated by a lever 22 within convenient reach of the driver of a machine.

Thus it will be seen that by manipulating the lever 22 the lamps through the medium of the heretofore mentioned devices may be swung vertically. The shaft 4 of each lamp has secured thereto an arm 23, these arms being connected by a pair of telescoping mem bers 24, one of which carries a set screw 25 adapted to bind against the other for accommodating adjustment of the members or .their disconnection, so that both lamps may be actuated simultaneously in an automatic manner now to be described. One of the members 24 has connected thereto a substantially L shaped link 25 connected to the turning mechanism 26 of the machine by having a pivotal connection with a finger 27 projecting from the wheel spindle of the turning mechanism 26;

In use the lights or lamps 1 may both be tilted simultaneously by raising or lowering the links 10, this raising or lowering of the links causing corresponding movement of :ating said link vertically for tilting the'rod' the rods 12 and consequent tilting of the headlights. As the rods 12 are disposed concentric with shafts 41- of the headlights for the greater portion of'their length, as

illustrated, and are slidable between the roll Z ers 11 the headlights may be'turned in either direction about their vertical axes and the rods 12 serve to guide and brace the lights during this turning movement.

Having described my invention, what I claim is:

1. In combination, a pair of headlights each mounted for vertical and horizontal swinging movements, an arcuate rod connected to each light, a link device including rollers supporting said rod, means for operand theclight connected thereto, and means for connecting said headlights to the steer ing mechanism of an automobile so as to be turned about their vertlcal axes 1n accordance with movement of said mechanism.

2. 'In combination, a pair of head lights each mounted for movement about a hori- 'zontal axis and about a verticalaxis, arcuate rods secured to the respective lamps and disposed concentric with the vertical axis 3. In combination,-a lamp mounted for movement about a horizontal axis and about a vertical axis, a link, means for operating said link vertically, and an arcuate rod secured to said lamp and disposed concentric with the vertical axis of movement thereof, said rod being operable so as to tilt the lamp about its horizontal axis in accordance with theoperation of said link while slidable through the link to permit turning of the lamp about its vertical axis. 7

In testimony whereofI affix my signature.

CHARLES E. DAILEY, SR."
